HI All! I’m trying out the Record, Save, and Play Moves on a Poppy Creature notebook. It records fine but the playback is rather jerky. Is this normal? Or should default playback be smooth? Using an Odroid XU4. I am getting a warning on initialising PoppyHumanoid() WARNING:pypot.dynamixel:DxlErr…

Thanks Pierre, Hope you had a good break. I’ve uploaded a video to youtube of poppy performing the idle loop. You can see the action is not entirely smooth. The motions i record are somewhat similar, a little jittery. The return_delay_time is set to 0 for all motors.(in dynamixel wizard) @Thot , …

It is not normal. Have you timeouts in Python logs ? Are you using one or two USB2AX ? Can you move your motors softly when there are in compliant mode (or swicth off) ?

I wasn’t getting timeouts when recording or playing , however i am just now because i have a broken wire to hip servo. This broken wire happened after the problem was already occurring. I’m using two USB2AX The motors are all smooth except chest x which I think might have overheated once. I may ha…

Hello John, have you found the solution? I have the same problem with my poppy humanoid and as you said it makes a little jittery. First I executed the same code that we can find in the Poppy Documentation but my start line doesn’t works it marks an error. So I tried with the Raspberry Pi 2 by this…

Hi Chibimoon, Sorry for the delay. No, I haven’t found a solution yet. I fixed my broken wire and tried both recording a movement and generating movement using sine wave. both were a bit jerky, and surprisingly, the recorded movement was a little better than the sine driven. The degree of jerki…

Hi @john don’t worry. I wonder if you use goal_position or goto_position. Because in the last weeks I was programming with both and I noticed a biggest difference in the motion when we use goto_position or goal_position.

Hey Thot I’m also using MX-28AT and the Odroid XU4 but when I tried to connect a single motor for test it the Python terminal returns an error pointing that the model number (for MX-28AT is 30) is not in the dicttionary of model numbers. Would you tell me please how you connected your robot? I’m us…

If you use MX-28AT, the code to use in the json configuration file is MX-28. the “AT” are only for hardware and communication protocol. Take care about pypot.Robot class, it does not work with only one motor. I advise you to do the same with two motors with the code MX-28.

Thanks Thot, I’ll try what you suggest. Again, thank you a lot. Greetings Thot :grinning:

Excuse me Thot, when I creat a PoppyTorso instance i get the error: OSError: Could not initalize robot: No suitable port found for ids [33, 34, 35, 36, 37, 41, 42, 43, 44, 51, 52, 53, 54]. These ids are missing [] ! Have you faced this error before?
